Investigations into suspected unexploded ordnance on Route Isabelle are expected to conclude within six weeks, with Home Affairs denying that the work had stopped.
The Committee said agreements have now been signed with a scientific branch of the British military to analyse what was found in the field earlier this summer.
A specialist survey by 6 Alpha Associates detected four “magnetic anomalies” buried eight metres deep in June.
The States said there is no risk to the public because they are buried so deep below the field’s surface.
Home Affairs admitted there had been a delay between the detections and the start of the next phase of analysis but said the results would be returned within four to six weeks.
But they criticised “public speculation that the work has stopped”.
Senior officers will consider the results with the island’s Military Liaisons to decide what to do next.
Deputy Marc Leadbeater, President of Home Affairs, said they were ensuring the work was done in a proportional and cost effective way.
“Public safety is of course a priority for the Committee, and that is why we have continued to ensure this work progresses.
“We did consider using a private contractor, but that would have cost the taxpayer a five-figure sum and only brought the work forward by a few weeks at most, so the cost could not be justified.”
Dave Le Ray, Director of Operations, Justice & Regulation, said officers have kept nearby residents informed on the progress and the next steps.
We have been endeavouring to involve a wide-range of experts in the surveys and assessments we have had carried out to date. We anticipate a further discussion taking place with the Military by December,” he added.
